The second foray into country music by Third Day frontman Mac Powell displays the same earthiness and conviction that’s earned him legions of fans in both the Christian and secular realms. Cowriting with such notables as Darius Rucker, Travis Tritt, and Sugarland’s Kristian Bush, Powell brings a Dixie-fried intensity to upbeat tracks like “Red Boots,” ”Summer Lovin’,” and “90 to Nothing” and fills ballads like “Sittin’ Here Talkin’ with You,” “Everything to Me,” and “I’ve Always Loved You” with a rough-hewn tenderness. First cut to last, Southpaw feels like a homecoming celebration for this Alabama native son.
